A man speeding past police in Agat last Saturday night was charged on Monday with illegal drug possession after officers found a bag with a crystalline substance in the car, according to a magistrate's complaint filed in the Superior Court of Guam.

Edward Joseph Herrera Sanchez, 27, drove past an officer in Agat at a high rate of speed and was pulled over, documents state.

Sanchez appeared to be under the influence

The officer noted Sanchez was the only person in the car and appeared to be under the influence of alcohol, according to court papers. Sanchez refused to submit to a field sobriety test, documents state.

When Sanchez got out of the car, the officer saw a small plastic resealable baggie with white crystalline substance on the driver's seat, documents state. The substance tested presumptive positive for an amphetamine-based substance, according to the court complaint.

Sanchez was charged with possession of a Schedule II controlled substance as a third-degree felony.
